This is the hilarious moment a pet owner takes his two cats for a walk by pushing them - inside a trolley. Father Nasir bin Mohd was fed up with the cats being stuck inside and wanted them to get some fresh air - without going missing. But instead of using a lead or carrying them, he had the ingenious idea of using his metal shopping trolley. Nasir laid a couple of towels down inside a metal stroller and pushed them down the pavement near the family home in Singapore.
